Global flooding is becoming an increasingly pressing issue as the impact of climate change increases. Significant changes in Earth’s temperature contribute to extreme weather phenomena, including excessive rainfall. In recent years, a number of regions around the world have experienced severe floods that have caused major damage to infrastructure, the environment and human life. Data shows that rising global temperatures are causing melting of polar ice, which is contributing to sea level rise. As sea levels rise, coastal areas become increasingly vulnerable to flooding. For example, cities such as Jakarta and Miami are facing serious threats due to the combination of land subsidence and rising sea levels. This exacerbates the potential for disaster when heavy rain hits. Additionally, chaotic weather patterns caused by climate change are triggering flooding in previously unaffected areas. Countries that often have moderate rainfall are now experiencing extreme rainfall that causes waterlogging and landslides. In this context, inadequate infrastructure is one of the factors causing increased vulnerability. Poor drainage systems in a number of big cities worsen the situation when heavy rain occurs. Floods not only cause physical damage, but also threaten public health. Floodwater is often contaminated with chemicals and pathogens, increasing the risk of infectious diseases such as diarrhea and leptospirosis. This impact is felt most by vulnerable communities who do not have access to adequate health services. In the long term, recovery from these disasters requires large costs and takes a long time, often disrupting economic development. Climate change also disrupts daily life, such as agricultural activities. Flooding causes damage to fields and crops, potentially reducing crop yields and increasing food prices. This trigger can cause food crises in various parts of the world, especially in developing countries that depend on traditional agriculture. Mitigation measures are very important to face this challenge. Sustainable infrastructure development, implementation of environmentally friendly technology, and increasing public awareness regarding climate change are necessary steps. Learning and implementing efficient water management techniques, such as rainwater harvesting, can also help reduce the risk of flooding. Collaborative efforts between governments, communities and non-governmental organizations are needed to formulate better policies to overcome the impacts of global flooding. Awareness of the importance of protecting ecosystems, such as mangrove forests, is no less crucial in efforts to prevent flooding. Overall, global flooding is a complex challenge due to the interaction between climate change and human activities. With the right steps, there is hope to mitigate the impact and build better resilience to natural disasters in the future.
